Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179690, here are decompositions:

3 + 179687 = 179690
19 + 179671 = 179690
31 + 179659 = 179690
67 + 179623 = 179690
97 + 179593 = 179690
109 + 179581 = 179690
127 + 179563 = 179690
157 + 179533 = 179690

Showing the first eight; more decompositions exist.
